    drm/nouveau/pmu/gm20b,gp10b: Fix Falcon bootstrapping · 89b34254
    Thierry Reding authored
    The low-level Falcon bootstrapping callbacks are expected to return 0 on
    success or a negative error code on failure. However, the implementation
    on Tegra returns the ID or mask of the Falcons that were bootstrapped on
    success, thus breaking the calling code, which treats this as failure.
    
    Fix this by making sure we only return 0 or a negative error code, just
    like the code for discrete GPUs does.
